(first embodiment)
Fig. 1 is the control block diagram of the utensil surveillance equipment of the first embodiment of the present invention.
In Fig. 1, Reference numeral 1 is identified at the flow detection unit of arranging in the fuel gas flow path in the gas meter, flow meter.Reference numeral 2 signs are constructed to the utensil of the Gas appliance of definite client's use and confirm the unit.Reference numeral 3 sign carbon dioxide output data storage cells, it is constructed to store for every kind of predetermined carbon dioxide output of Gas appliance as database.Reference numeral 4 sign carbon dioxide output computing units, it is constructed to calculate, add up and the storage carbon dioxide output based on the gas flow of the data relevant with the carbon dioxide output of the Gas appliance that is selected from the carbon dioxide output data storage cell, Gas appliance and gas consumption time.Reference numeral 5 sign timer units, its given period that is constructed to whenever be scheduled to outputs to carbon dioxide output computing unit 4 with signal.Carbon dioxide output computing unit 4 is provided when receiving said signal, on display unit 6, to show the carbon dioxide output data.
The operation and the effect of utensil surveillance equipment are described now.Flow detection unit 1 is disposed in the fuel gas flow path (not shown in the accompanying drawings) of gas meter, flow meter, and detects gas flow.According to the gas flow signal, utensil is confirmed 2 study flow value and the gas consumption times of unit, thereby confirms the Gas appliance that the client uses, and output is by the gas flow signal of this Gas appliance use.Carbon dioxide output data storage cell 3 is stored based on every kind of predetermined carbon dioxide output of Gas appliance as database.Carbon dioxide output computing unit 4 be based on the gas consumption time that receives the gas-flow that is selected from the carbon dioxide output data relevant of carbon dioxide output data storage cell 3, selected Gas appliance when confirming the signal of unit 2 and selected Gas appliance with Gas appliance from utensil calculate, accumulative total and storage carbon dioxide output.Whenever predetermined section preset time of timer unit 5 (for example, one month, collect time period etc. of combustion gas expense therebetween) outputs to carbon dioxide output computing unit 4 with signal.When receiving said signal, carbon dioxide output computing unit 4 shows the carbon dioxide output data on display unit 6.Therefore, can confirm the carbon dioxide output that the client uses Gas appliance to produce.Therefore, can solve to what increase and understand the society need of aforementioned information for expectation about the background of the care of earth environment.
The database of the carbon dioxide output that carbon dioxide output data storage cell 3 can be constructed to store in advance for every kind of Gas appliance.Change the database of the carbon dioxide output that therefore, can solve before database increases carbon dioxide output, causes etc. by improvement for utensil from the Gas appliance of original newtype.Therefore, can confirm the carbon dioxide output that the user uses Gas appliance to produce from the carbon dioxide output database that upgrades.Therefore, can confirm more accurate carbon dioxide output.
When the carbon dioxide output of accumulative total and storage had surpassed the value of preset carbon dioxide output, the carbon dioxide output computing unit was to this result of outside output.Therefore, can confirm that this carbon dioxide output has surpassed set-point (for example, considering the influence of environment and definite standard value), and give notice whether this notice can be shown the carbon dioxide output that the client produces clearly big.Based on this information, when use producing the utensil of big carbon dioxide output, can promote the replacing of utensil to buy, and when the gas quantity of client's consumption is big, can cause the selfdiscipline on operating time of frequency of utilization and Gas appliance of Gas appliance.Therefore, can reduce the carbon dioxide output that produces through the use Gas appliance.
When the carbon dioxide output of each accumulative total and storage surpassed the value of a plurality of preset carbon dioxide outputs, carbon dioxide output computing unit 4 was to this result's of outside output signal.When from the set-point of little carbon dioxide output to (for example as the set-point of peaked carbon dioxide output; Consideration for the influence of environment and definite standard value) when order is provided with the value of a plurality of preset carbon dioxide outputs, can report the increase of carbon dioxide output continuously.
Therefore, can show increase clearly by stage ground by the carbon dioxide output of client's generation.Therefore, when use producing the utensil of big carbon dioxide output, promote the replacing of utensil to buy more easily, and the gas quantity that consumes as the client is when big, asks selfdiscipline more easily for the operating time of the frequency of utilization of Gas appliance and Gas appliance.Therefore, can reduce through using the carbon dioxide output of Gas appliance.When a plurality of values of carbon dioxide output are set to (for example surpass said set-point; Consideration for the influence of environment and the value of definite standard) value the time; Also can send warning, maybe can forbid the use of Gas appliance through cutting off combustion gas to the outside about quite big carbon dioxide output.Therefore, when use producing the Gas appliance of big carbon dioxide output, can promote the replacing of utensil to buy, and the gas quantity that consumes as the client is when big, requirement is for the selfdiscipline of the operating time of the frequency of utilization of Gas appliance and Gas appliance more easily.Therefore, can reduce Gas appliance and use the carbon dioxide output that causes.When being set to, the value of a plurality of carbon dioxide outputs (for example exceeds set-point; Consideration to the influence of environment and definite standard value) value the time; Can also send alarm to the outside, perhaps can forbid the use of Gas appliance through cutting off combustion gas about sizable carbon dioxide output.Therefore; When using the utensil that produces big carbon dioxide output; Can promote the replacing of utensil to buy, and when the gas quantity of client's consumption is big, can further promote to require selfdiscipline for the operating time of the frequency of utilization of Gas appliance and Gas appliance.
Can show information about the carbon dioxide output of accumulative total and storage.Therefore, when watching display unit 6, the people relevant with Gas appliance (for example, Gas appliance retailer, domestic consumer etc.) can understand the carbon dioxide output when watching display.Therefore; When using the utensil that produces big carbon dioxide output; Promote the replacing of utensil to buy more easily, and the gas quantity that consumes as the client is when big, requirement is for the selfdiscipline in operating time of the frequency of utilization of Gas appliance and Gas appliance more easily.
Can be to the information of outside output about the carbon dioxide output of accumulative total and storage.Through acquired information by this way, can confirm the carbon dioxide output of accumulative total and storage in real time.In addition; Through the explanation etc. of chargeing of the combustion gas with this information is provided; When using the utensil that produces big carbon dioxide output; Promote the replacing of utensil to buy more easily, and the gas quantity that consumes as the client is when big, requirement is for the selfdiscipline of the operating time of the frequency of utilization of Gas appliance and Gas appliance more easily.In addition, can via such as the communication network of telephone wire to outside report information such as the fuel gas shutoff equipment of gas supply merchant's warning system (not shown).
The Japanese patent application that present patent application was submitted in Japan based on May 20th, 2008 (application No.2008-132129), its entirety is incorporated into here by reference.
